[GreenKeys] TT-4/TG Stencil Machine

[Duncan Brown]

Kevin,

Square keys are normal for all the TT-4 models except the "A".  And they 
are generally all olive/brown drab non-crackle finish.  There is an 
adjustment on the back of the print carriage - a grooved nut that rides 
in a bar that does the printing.  But is could be more complicated than 
that. Try turning the motor by hand to see what it is doing.

You can download manuals at http://rattrig.com/manuals/tm%27s.htm.

have fun & good luck,
